I understand that it is an important greenhouse gas...
But what regulates the amount of water vapour in the atmosphere? Is it temperature? ...and by what relationship? ...directly proportional?
And if it is temperature, wouldn't an increase in temperature increase the amount of water vapour in the atmosphere, leading to further warming as a feedback?
This is my understanding of 'water vapour feedback' but beyond this I know almost nothing about the science of how water vapour affects climate.
So, what can anyone tell me about this, particularly in respect of man made global warming which I believe is happening.
Thanks in advance...
